BACKGROUND OF THE INVENTION

[0001] 1. Technical Field

[0002] The present disclosure relates to liquid crystal displays, moreparticularly, liquid crystal displays having polarizing or compensatingfilms.

[0003] 2. Discussion of the Related Art

[0004] A liquid crystal display (LCD) includes a pair of upper and lowerpanels, and a liquid crystal layer interposed therebetween for housingliquid crystals. The upper panel is provided with a common electrode andcolor filters; the lower panel is provided with pixel electrodes andthin film transistors (TFTs). The liquid crystals in the liquid crystallayer are subjected to an electric field generated between electrodes ofthe upper and lower panels. The variation of the field strength changesthe molecular orientations of the liquid crystals and the changedmolecular orientations in turn change the transmittance of light passingthrough the liquid crystal display such that desired images areobtained.

[0005] Light, an electromagnetic wave, oscillates in directionsperpendicular to its moving direction. Generally, the oscillation oflight is not confined or biased to a particular direction. Thus,polarizers are used to direct the transmitted light. Generally,polarizers are disposed exterior to the upper or lower panels such thatthe light transmitted through the liquid crystal layer is polarized.

[0006] A compensation film can also be interposed between the polarizerand the upper and lower panels to enhance viewing angle and/or colorinversion features of an LCD. The compensation film retards or shiftsone component of the light to convert the elliptically polarized lightgenerated by the liquid crystal display cell into linear polarizedlight, which can be effectively polarized by the polarizer.

[0007] Typically, a polarizer and a compensation film are separatelydisposed in an LCD, by affixing to the panel.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0029] The present disclosure will be described more fully hereinafterwith reference to the accompanying drawings, in which preferredembodiments of the disclosure are shown. This disclosure may, however,be embodied in many different forms and should not be construed as beinglimited to the embodiments set forth herein.

[0030] The liquid crystal displays according to embodiments of thepresent invention will now be described with reference to the drawings.

[0031]FIG. 1 is a sectional view of an LCD according to an embodiment ofthe present disclosure. As shown in FIG. 1, an LCD includes a lowerpanel 110, an upper panel 210, and a liquid crystal layer 3 for housingliquid crystals interposed between the lower panel 110 and the upperpanel 210. The lower panel 110 includes a TFT array panel (not shown)and the upper panel 210 includes a color filter (not shown). Alignmentlayers (not shown) are disposed on the two panels to anchor the liquidcrystals. Electrodes (not shown) for generating electric field areformed on the two panels. The liquid crystals are preferably aligned invertical alignment (VA) mode. In VA mode, the molecules of liquidcrystals are normally aligned at right angles to the panels, swingingthrough 90 degrees to lie parallel with the panels in the presence ofthe electric field.

[0032] A lower polarizer 12 is disposed under the lower panel 110. Thelower polarizer comprises a polarizing medium 12 b interposed betweentwo supporting films 12 a and 12 c. As shown in FIG. 1, the supportingfilm 12 c is positioned closer to the lower panel 110 as compared to thedistance between the supporting film 12 a and the lower panel 110.

[0033] A compensation film 23 is disposed on the upper panel 210 and anupper polarizer 22 is disposed on the compensation film 23. The upperpolarizer 22 includes two supporting films 22 a and 22 c and apolarizing medium 22 b.

[0034] The supporting films 12 a, 12 c, 22 a, and 22 c are preferablymade of tri-acetyl cellulous (TAC) or cellulous acetate propionate(CAP). The polarizing mediums 12 b and 22 b are preferably made ofpolyvinyl alcohol (PVA).

[0035] The compensation film 23 is preferably formed as a thin film madeof a material having different values for Nx, Ny, and Nz. Nx denotes therefractive index in the direction of its major axis. Ny denotes therefractive index in the direction of its minor axis. Nz denotes therefractive index in the direction perpendicular to the major and minoraxis.

[0036] Thin films such as the lower polarizer 12, the compensation film23, and the upper polarizer 22 exhibit phase retardation characteristicswhich can be used for enhancing viewing angle and/or color inversion.Phase retardation of a thin film is calculated according to thefollowing equations:

Ro=(Nx−Ny)d

[0037]$R^{\prime} = {\left( {\frac{{Nx} + {Ny}}{2} - {Nz}} \right)\quad d}$

[0038] Here, Ro denotes phase retardation in the horizontal direction.R′ denotes phase retardation in the vertical (thickness) direction.Small d denotes the thickness of the thin film.

[0039] According to an embodiment of the present disclosure, thesupporting film 22 a can be made with Ro which is about 0 nm to about 5nm and R′ which ranges between about 50 nm and about 60 nm. Thecompensation film 23 on the upper panel 210 can be made with Ro rangingbetween about 40 nm and about 60 nm and R′ ranging between about 80 nmand about 100 nm. Thus, R′ of the thin film on the upper panel 210 intotal ranges between about 130 nm and about 160 nm.

[0040] The supporting film 12 c of the lower polarizer 12 can be madewith Ro which is about 0 nm to about 5 nm and R′ ranges between about100 nm and about 140 nm. Having such characteristics, the lowerpolarizer 12 increases phase retardation and additional compensationfilms are not necessary under the lower panel 110.

[0041] Thus, the same overall effect as was achieved in conventional artusing compensation film is achieved by the lower polarizer 12 withoutusing compensation film. Although description of the above embodiment isdirected to upper and lower polarizers, one ordinary skilled in the artcan readily appreciate that the upper and lower panels and associatedpolarizers and films are interchangeable, without degradation inretardation characteristics.

[0042] Thin films of zero (0) Ro, i.e., thin films having no phaseretardation in their horizontal direction, can be fabricated bylamination using a roll. FIG. 2A shows an elongation direction for thepolarizing medium 22 b. FIG. 2B shows an elongation direction for thecompensation film 23.

[0043] As shown in FIGS. 2A and 2B, an absorption axis B of the upperpolarizer 22 along which the light vanishes is the same as an elongationdirection A of the polarizing medium 22 b. A polarization axis (notshown) of the upper polarizer 22 along which the light penetrates isperpendicular to the elongation direction A of the polarizing medium 22b. A phase retardation axis D of the compensation film 23 havingnon-zero value of Ro should be perpendicular to the absorption axis B ofthe upper polarizer 22. Therefore, the compensation film 23 ispreferably laminated in the direction C perpendicular to the elongationdirection A of the polarizing medium 22 b.

[0044]FIG. 3 is a sectional view of an LCD according to anotherembodiment of the present disclosure. As shown in FIG. 3, an LCDincludes a lower panel 110, an upper panel 210, and a liquid crystallayer 3 for housing liquid crystals interposed between the lower panel110 and the upper panel 210. The liquid crystals are preferably alignedin vertical alignment (VA) mode. A lower polarizer 12 is disposed on thelower panel 110. The lower polarizer comprises a polarizing medium 12 binterposed between two supporting films 12 a and 12 c. The upperpolarizer 22 includes two supporting films 22 a and 22 c and apolarizing medium 22 b.

[0045] The supporting film 22 a is preferably formed as a thin film madeof a material having different values for Nx, Ny, and Nz.

The supporting film 22 a can be made with Ro which ranges betweenabout 40 nm and about 60 nm and R′ which ranges between about 120 nm andabout 160 nm. The supporting film 12 c can be made with Ro which isabout 0 nm to about 5 nm and R′ which ranges between about 100 nm andabout 140 nm.

[0046] The lower polarizer 12 increases phase retardation because thesupporting film 12 c has R′ ranging between about 100 nm and about 140nm. The upper polarizer 22 increases phase retardation because thesupporting film 22 a has Ro ranging between 40 nm and 60 nm and R′ranging between about 120 nm and about 160 nm. Thus, a compensation filmis neither necessary under the lower panel 110 nor above the upper panel210.

[0047]FIG. 4A shows the elongation direction for the polarizing medium22 b. FIG. 4B shows the elongation direction for the supporting film 22a. As shown in FIGS. 4A and 4B, an absorption axis B of the upperpolarizer 22 along which the light vanishes is the same as an elongationdirection A of the polarizing medium 22 b. A polarization axis (notshown) of the upper polarizer 22 along which the light penetrates isperpendicular to the elongation direction A of the polarizing medium 22b.

[0048] A phase retardation axis D of the supporting film 22 a havingnon-zero value of Ro is the same as an elongation direction C of thesupporting film 22 a. The phase retardation axis of the supporting film22 a having non-zero value of Ro should be perpendicular to theabsorption axis B of the upper polarizer 22. The supporting film 22 acan be laminated in the direction C perpendicular to the elongationdirection A of the polarizing medium 22 b.

[0049] According to still another embodiment of the present disclosureas shown in FIG. 5, the supporting film 12 c and the supporting film 22a are preferably formed as thin films made of a material havingdifferent values of Nx, Ny, and Nz. The supporting films 12 a and 22 ccan be made of tri-acetyl cellulous (TAC) and the polarizing mediums 12b and 22 b can be made of poly-vinyl alcohol (PVA).

[0050] Both the supporting film 12 c and the supporting film 22 a can bemade with Ro which ranges between about 40 nm and about 60 nm and R′which ranges between about 120 nm and about 160 nm. The lower polarizer12 increases its phase retardation because the supporting film 12 c hasRo ranging between about 40 nm and about 60 nm and R′ ranging betweenabout 120 nm and about 160 nm. The upper polarizer 22 increases itsphase retardation because the supporting film 22 a has Ro rangingbetween about 40 nm and about 60 nm and R′ ranging between about 120 nmand about 160 nm.

[0051]FIG. 6A shows the elongation direction for the polarizing medium12 b and the polarizing medium 22 b. FIG. 6B shows the elongationdirection for the supporting film 22 a and the supporting film 12 c.

[0052] As shown in FIGS. 6A and 6B, an absorption axis B of the upperpolarizer 22 along which the light vanishes is the same as an elongationdirection A of the polarizing medium 22 b. A polarization axis (notshown) of the upper polarizer 22 along which the light penetrates isperpendicular to the elongation direction A of the polarizing medium 22b.

A polarization axis (not shown) of the lower polarizer 12along which the light penetrates is perpendicular to the elongationdirection A of the polarizing medium 12 b.

[0053] A phase retardation axis D of the supporting film 22 a havingnon-zero value of Ro is the same as an elongation direction C of thesupporting film 22 a. The phase retardation axis D of the supportingfilm 22 a having non-zero value of Ro should be perpendicular to theabsorption axis B of the upper polarizer 22. A phase retardation axis Dof the supporting film 12 c having non-zero value of Ro is the same asan elongation direction C of the supporting film 12 c. The phaseretardation axis D of the supporting film 12 c having a non-zero valueshould be perpendicular to the absorption axis B of the upper polarizer22.

[0054] The supporting film 22 a can be laminated in the direction Cperpendicular to the elongation direction A of the polarizing medium 22b. The supporting film 12 c can be laminated in the direction Cperpendicular to the elongation direction A of the polarizing medium 12b.

As shown in FIG. 7, an LCDincludes a lower panel, an upper panel 210, and a liquid crystal layer 3for housing liquid crystals interposed between the lower panel 110 andthe upper panel 210. The liquid crystals are preferably aligned invertical alignment (VA) mode. A lower polarizer 12 is disposed on thelower panel 110. The lower polarizer comprises a polarizer medium 12 binterposed between two supporting films 12 a and 12 c. The upperpolarizer 22 includes two supporting films 12 a and 12 c. The upperpolarizer 22 includes two supporting films 22 a and 22 c and apolarizing medium 22 b.

[0056] The supporting film 22 a is preferably formed as a thin film madeof a material having different values for Nx, Ny, and Nz. The supportingfilms 12 a, 12 c, and 22 c can be made of tri-acetyl cellulous (TAC) andthe polarizing medium 12 b and 22 b can be made of poly-vinyl alcohol(PVA). The supporting film 22 a can be made with Ro which ranges betweenabout 50 nm and about 70 nm and R′ which ranges between about 210 nm andabout 250 nm. The supporting film 12 c can be made with Ro which isabout 0 nm to about 5 nm and R′ which ranges between about 50 nm andabout 60 nm.
